Add password to an existing zip file

Question

is there a way to add a password to an existing .zip file in Ubuntu?

Answer 1

To encrypt a zip file after it has been created, you can use zipcloak

The syntax is:

zipcloak foo.zip

You will be prompted to give the password for the zip file called foo.zip

You can zip a file(s) in creating a zip file using the -e parameter i.e.

zip -e foo.zip file1
